The ohed ule referred to in these Letters Patent and .making m of thesame.

a I, JAMES H. NEWTON, of Holyoke, county of Hamp: den, Oommonwealtho't'Massachusetts, have invented a new and useful Process ofManufacturingCombined Cloth and Paper, of which' the following is aspecification.

My improved process consists in first preparing the cloth with a heavysizing of potato starch on each side, or potato starch upon one side,and potato starch mixed with glue in solution uponftheother side. It

may then be calendered, or chine without v I then unite thispreparedcloth with-the paper in the ordinary paper-machine, while, the paper is.in a state of pulp, and' this combined sized cloth and sheet ofpaper-pulp passeson' to the dryingrolls.

The first drier or the first two or threeare kept'at a low degree oftemperature, 'so'as to set the starch without bu'rningor'baking it,thereby preventing dark spots and motes. This low temperature Iaccomplish either by partially shutting off the steam from the interiorof'the driers, or by covering the said drier with a. non-conductingsubstance.

This combined paper and cloth then passes over the pass to thepaper-maremaining driers, and thr'oilgh calenders, the whole processimparting to the fabric'a laundry finish.

By this process the paper andcloth are evenly and surely combined, andthe fabric comesifrorn the calenders clean, the cl'oth and paper firmlyadhering, and with the desired finish.

By along series of experiments I have fonndvthat by the use of theabove'process, and starch for sizing,

the resnltdesired could be accomplished, and inino' other way that Ihave been able to discover. i

The process herein describel of manufactnrims,combined paper/and :cloth, consisting in' the useof sized cloth, unitedin the paper-machine \vitlrpulp, the whole being passed over driers ofdifferent temperatures and through calender-s, substautiall y as setforth. 2. The use-0f potato starch, with orwithout glue, in combinedpaper and cloth fabric, for the purpose of uniting firmly the twomaterials and giving the desired finish, in the manner described..Witnesses: JAMES H.
